LG BW 400 AFR G2

Summary

Product identification

LG BW 400 AFR G2 brackish water reverse osmosis (RO) membranes are designed for municipal and industrial applications. These elements incorporate innovative Thin Film Nanocomposite (TFN) technology, providing superior performance with intrinsic anti-fouling properties. They are described as anti-fouling, high rejection, high flow, and high durability, equipped with fouling tolerant low differential pressure (dP) spacer technology.

The LG BW 400 AFR G2 offers enhanced fouling resistance, high rejection, flow, and durability, aiming to reduce total cost of ownership. They are suitable for high salinity brackish water and wastewater reuse applications with challenging feed water, utilizing state-of-the-art feed spacer technology to reduce differential pressure and cleaning frequency.
